The Cato Institute's David Boaz thinks Rudy Giuliani would be a most un-libertarian president, particularly given the expansion of executive power under President Bush.

Throughout his career, Giuliani has displayed an authoritarian streak that would be all the more problematic in a man who would assume executive powers vastly expanded by President Bush. . . .

Giuliani's view of power would be dangerous at any time, but especially after two terms of relentless Bush efforts to weaken the constitutional checks and balances that safeguard our liberty.
